This package serves as a set of common types to be shared between packages like @truffle/dashboard-message-bus and @truffle/dashboard-message-bus-client
If you are building a package that needs to interface with the Dashboard or message bus, you can install this package from NPM.
npm install @truffle/dashboard-message-bus-common
yarn add @truffle/dashboard-message-bus-common
Right now there are very few message types. The most important one is "provider", which sends RPC requests for the dashboard-provider. Other message types are "invalidate", which can be sent to invalidate earlier messages, and "log", which is sent by the message bus to send log messages over the wire. The interfaces of these messages are defined inside of this package, from where they can be imported by consumers.
To add additional message types, the interface for the new message type should be defined in this package under lib/messages.ts. To use these new messge formats, support needs to be added to any consuming packages such as @truffle/dashboard as well.
